Embodiment Construction

[0016] A kind of zeolite ore template prepares the method for porous carbon, adopts following steps:

[0017] Step 1: Preparation of charcoal / template complex:

[0018] Use zeolite ore as a template and sucrose as a carbon source; put 5g of zeolite ore powder in a beaker, add 20mL of sucrose, deionized water, and sulfuric acid solution in total, shake on a shaker for 2 hours, and filter; put the solid part in air at 100°C Heating under low temperature for 4 hours, then raising the temperature to 150°C and keeping it for 2 hours to polymerize and solidify the sucrose; put the cured product into a tubular atmosphere furnace, and under the protection of nitrogen, raise the temperature to 850°C at a rate of 5°C / min, carbonize for 5 hours, to obtain a carbon / template complex;

[0019] Step 2: Preparation of porous carbon from the carbon / template composite:

[0020] Treat the complex in concentrated hydrofluoric acid for 3 hours, wash it and then treat it with hydrochloric acid to...

Abstract

The invention relates to the technical field of application and preparation of functional materials, in particular to a method of using a zeolite template to prepare porous carbon, comprising the steps of preparing a carbon / template composite with zeolite; preparing porous carbon with the prepared carbon / template composite. A template is made with natural zeolite to prepare medium- and large-poretemplate carbon with wide particle size distribution. The template carbon has specific surface area of 41 lm<2> / g and medium-pore rate of 66%; in H2SO4 medium, the template carbon has good high-rate performance; in case of scanning speed of 1 mV / s, the template carbon has specific capacity of 185 F / g; when the scanning speed is increased to 500 mV / s, the specific capacity is still 133 F / g, the capacity retention ratio is 72%, and a good scanning curve is maintained.

Description

technical field [0001] The invention relates to the technical field of application and preparation of functional materials, in particular to a method for preparing porous carbon with a zeolite ore template. Background technique [0002] Supercapacitors with porous carbon electrodes are expected to become new energy sources for applications such as power vehicles and power storage due to their high energy and power densities. In order to obtain high energy and power density, porous carbons are required to have high specific surface area, large pore size and suitable surface functional groups. Under these conditions, carbon aerogels and template carbons with medium and macroporous structures are widely used in the research of supercapacitors. Among them, template carbon has received more attention due to its tunable pore size. However, traditional template carbons generally use porous silicon materials with regular pore diameters. Most of these templates are artificially syn...
